Converting Port Reference Impedance In Differential Mode; Converting Port Reference Impedance In Common Mode - Agilent Technologies ENA Series User Manual

Converting port reference impedance in differential mode

If you turn on the differential port impedance conversion function, the port reference
impedance in the differential mode is converted to an arbitrary value specified with this
function instead of the value in Figure 7-17.
Procedure to Turn On/Off Differential Port Reference Impedance Conversion
Function
Step 1.
Step 2. Press
You can only turn on or off Differential Port Impedance Conversion for all of the balanced
ports together, not for each port individually. If you want to turn off only a specific port, set
the reference impedance of the port to the value in Figure 7-17.
Procedure to Set Differential Port Reference Impedance
Step 1.
Step 2. Specify the port reference impedance in differential mode.
• Select the balanced port from
to set the differential port reference impedance in "Real" format.
• Select
or
impedance in "Complex" format.
NOTE Ports 1, 2, and 3 refer to the logical ports 1, 2, and 3.

Converting port reference impedance in common mode

If you turn on the common port impedance conversion function, the port reference
impedance in the common mode is converted to an arbitrary value specified with this
function instead of the value in Figure 7-17.
Procedure to Turn On/Off Common Port Reference Impedance Conversion
Step 1.
Step 2. Press
You can only turn on or off Common Port Impedance Conversion for all of the ports
together, not for each port individually. If you want to turn off only a specific port, set the
impedance of the port to the value in Figure 7-17.
Procedure to set common port reference impedance
Step 1.
Step 2. Specify the port reference impedance in common mode.
